UGH, that stinks!!!! We fly direct from Boston, always, so I can't feel your pain...but the thought of a layover that long gives me anxiety. What are they thinking? When are you going? Hopefully the flight times will change - they always change on us at least 2-3 times from the time we book.
Once I get to the airport and I'm ready to go home, I want to GO HOME - not sit in the airport for hours on end.
Maybe it's time for you to inquire about changing to a nonstop out of Boston? I think I would.
